Metal–organic frameworks (MOFs) are microporous or mesoporous materials consisting of metal ions/clusters (metallic centre) coordinated to organic ligands (linkers). MOFs are relatively new class of crystalline, porous materials, which have been studied since 1998 as effective adsorbents. MOF materials feature large surface area and pore volume, which make them attractive for various applications, e.g. gas separations, energy storage, catalysis, drug delivery, CO2 capture and luminescence. Among various porous adsorbents MOFs have received particular attention due to their excellent adsorption properties as well as tremendous opportunities in tailoring their composition and structure [1].
In this work two MOFs are presented: MOF-5 (Zn), systematic name: Zinc-1,4-benzenedicarboxylate and ZIF‑8 (ZnO–Zn), systematic name: Zinc-2-methylimidazole synthesized solvothermally in accordance to the procedures presented in the work [2]. Physicochemical properties of obtained MOF materials were compared with commercial material Basolite Z377 (Zn) (systematic name: Zinc-1,3,5-tri (4-carboxyphenyl) benzoate).
The surface properties of MOFs were characterized by: nitrogen adsorption isotherms, scanning electron microscopy (SEM), X-ray diffraction (XRD) analysis. The pore size distribution functions (PSDs) were calculated by the non-local density functional theory method (NLDFT). Also, the studied MOFs samples were characterized using the termogravimetry (TG, DTG) and differential thermal analysis (DTA) methods. Additionally, chemisorption tests were performed on synthesized MOFs materials and commercial material.
